In contrast with the DMX interface "with FT245", this board does not have the FT245RL chip on board.

The board will have a short connector soldered to the board. This allows you to mount it on a raspberry pi model A (that includes A+). We provide you with an extension connector to mount it on a raspberry pi B. (in the past you had tell us which one you'd want). When you select "for zero" we will leave that connector unsoldered. We provide you with a female 2x13 and a male 2x20. If you want you can then solder 2x13 of that male connector on the topside of our board, and the female on the bottom of the zero. Or you can put the 2x20 on the raspberry pi bottom and the female on our board. Or you can mount it in the classical way with the male headers on the top of the zero, and the female on the bottom of our board. Whatever you like!

This normally allows you to use this with the OLA software on the raspberry pi to work with DMX hardware. However the OLA software has not (yet) implemented the RX (receiving) part of the DMX protocol for this hardware. The board "with FT245" proves that this board together with the 'pi are physically capable of recieving DMX messages, it is just that the software is not yet written.
